This is the hilarious moment a group of friends at a bachelor party in Sweden played a bungee jump prank on the groom.

The mean pals led the groom blindfolded down a small jetty on a lake outside Stockholm and told him that he was going to do a bungee jump.

When they got to the end of the jetty, they counted down from ten and the groom dived off the jetty into the icy water.

Unfortunately, he ignored instructions to jump feet-first and hurt the top of his head.
